Abstract: A display panel includes a substrate having a first area, a second area, and a third area disposed between the first area and the second area. A plurality of display elements are disposed in the second area. The plurality of display elements includes two display elements spaced apart from each other with the first area disposed therebetween. Each of the plurality of display elements includes a pixel electrode, a counter electrode, and an intermediate layer disposed between the pixel electrode and the counter electrode. A separator is located in the third area and includes at least one reverse-tapered inclined surface. An inorganic layer is disposed on the separator. At least one sub-layer included in the intermediate layer is discontinuous across the separator.
